Structural and Spectroscopic Characterization of Modular Photoreceptors
… I also present my work in characterizing four spectroscopically distinct CBCRs from the same multi-sensor photoreceptor protein, both in isolated forms and in the full-length context. Based on spectral and structural studies, I discuss how bacterial signaling proteins combine different sensor …

Spectroscopic characterization of molecular and atomic iodine
This research looks to characterize molecular and atomic iodine to benefit to the ability of molecular iodine to act as a biocidal agent. There is much literature on the topic of iodine as a bacterial suppressant and the effectiveness of various mixtures. However, there is little research available …

Electron spectroscopic characterization of corrosion reactions of active metal systems.
The corrosion chemistry of two active-metal systems has been studied primarily with X-ray Photoelectron Spectroscopy. First, the interaction of metallic lithium thin films with simple glass surfaces was investigated. Li was deposited on SiO₂, sodium silicate, potassium silicate, and B₂O₃ glasses in …
